Product details
Overview
F271-BAG5-T-TR from STMicroelectronics is a 16-bit automotive-grade MCU featuring a 64 MHz CPU, 256 KB Flash memory, 10/18 KB XRAM, dual CAN 2.0B interfaces, and a 24-channel 10-bit ADC with 3 µs conversion time - deployed in engine control units and industrial motion controllers requiring deterministic real-time response.
For engineers reviewing the F271-BAG5-T-TR datasheet, F271-BAG5-T-TR pinout, F271-BAG5-T-TR application, or F271-BAG5-T-TR equivalent, key selection criteria include CAN bus arbitration support, MAC unit performance for motor control algorithms, Flash protection register configuration, and PQFP144 package thermal dissipation in extended temperature environments.
Technical Context
The ST10F271B core implements a 16-bit CISC architecture with hardware multiply-accumulate (16×16 → 40-bit), single-cycle context switching, and 56 interrupt sources with 15.6 ns sampling resolution. Its external bus controller supports five chip-selects and hold-acknowledge arbitration for multi-master systems.
Dual CAN 2.0B modules operate on one or two busses (64 or 2×32 message objects), with C-CAN firmware implementation enabling time-triggered communication. The 24-channel ADC uses programmable sampling windows and supports simultaneous capture with timer-triggered sequencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST10F267 | 128 KB Flash, 8 KB XRAM, single CAN, no XPWM unit | Limited to simpler body electronics or gateway nodes without motor control | Select when cost-sensitive designs omit dual CAN or advanced PWM features |
| Infineon C167CR-LM | 16-bit C166 core, 256 KB Flash, single CAN, 16-channel ADC, no MAC unit | Suitable for non-DSP-intensive control but lacks hardware acceleration for motor algorithms | Choose for legacy C166 toolchain compatibility where MAC performance is not required |
Compared with ST10F271B, ST10F267 reduces CAN capability and memory while lowering BOM cost; C167CR-LM offers comparable Flash but lacks MAC acceleration and dual CAN, making it less suitable for high-dynamics motor control or redundant bus architectures.

FAQ
Is F271-BAG5-T-TR pin-compatible with other ST10F271 variants?
Yes - F271-BAG5-T-TR shares identical PQFP144 pinout with ST10F271B and ST10F271E. Differences are limited to Flash size (256 KB vs. 128 KB in some revisions) and XRAM capacity (10 KB vs. 18 KB), both managed via software configuration registers rather than pin strapping.
What is the maximum operating temperature range for this device?
F271-BAG5-T-TR is qualified for −40°C to +125°C ambient operation per its automotive grade specification. This rating is validated across all electrical parameters in the datasheet's "Recommended Operating Conditions" table (Section 24.2), including Flash write/erase endurance at temperature extremes.
Does this MCU support JTAG debugging?
No - F271-BAG5-T-TR uses ST's proprietary single-wire debug interface (SWD) via the BOOT pin, not IEEE 1149.1 JTAG. Debug access requires ST-LINK/V2 or compatible adapters and is enabled only when the BOOT pin is held low during reset.
Can the internal PLL be bypassed for direct oscillator input?
Yes - the PLL can be disabled via the PLLCON register, allowing direct use of the 4–8 MHz external crystal or external clock signal on XTAL1. In bypass mode, the CPU clock derives directly from the oscillator source, reducing jitter but limiting maximum frequency to 8 MHz unless an external high-speed clock is applied.
